An installation reacts to human presence.
Placed in the west wing of the CFA hall, the tunnel itself reacts to human presence by folding and unfolding on its own while controlling the apertures, allowing for a a gradiant-like-variation of the size of the apertures along the whole tunnel. The reaction happens following the path of a person walking inside to offer different lighting experience through the tunnel. Depending where person stands, the modules next to that area open up slowly, surrounding the person with more ambient light.
